a visit to Cantillon can be very interesting. The Lambic and Geuze beers are very traditional and have only been commercialized relatively recently, so there are still numerous family owned breweries around. Especially in Brussels. They are not to everyones taste though.
I am not that familiar with Brussels, but it looks like the hotel is right in the middle of the European quarter. That area gets pretty much deserted at night. Personally I would not leave my bike outside overnight. Anyone with less than good intentions would have plenty of time to lift it in the back of a van without anyone noticing.
There's probably 101 things you could still visit, but nothing I can think of right now. Perhaps the Butte du Lyon. Although, except for the Lion there's not much else to see there. The museum is just plain boring. But the brasseries make it a nice lunch stop.
If you're into overpriced design nick-nacks sold in Brussels visit the "Zavel". Shops are open on Sunday as well.
